Test build - non official

This is a test build to make srt handling more robust. Current tool does not like debug srt files

Added

• Save OSD and SRT options between program runs.
• Custom position and text size of SRT data.
• Option to adjust OSD playback speed to correct for OSD lag with <=32.37.10 firmware.
• Check for app updates during startup.
• Hide/mask OSD elements from the rendered video (demo).
• Tooltips explaining options and settings.

Changed

• When loading a SRT file with distance data the distance checkbox doesn't get automatically checked.
• Options sections can be collapsed to save screen space.
